Description

Technical Field

[0001] This application relates to the field of oral scanning technology, specifically to an oral cavity opener, an oral cavity opener assembly, and a camera device. Background Technology

[0002] When taking dental images with a camera, a mouth opener is needed to open the lips. The mouth opener includes an opening with a through hole for light to pass through. The opening is directly connected to the main unit, which greatly restricts the position of the through hole relative to the main unit and makes it difficult to apply disposable consumables (such as isolation covers) to the mouth opener. Utility Model Content

[0003] In view of the above problems, this application provides an opening device, an opening assembly, and a camera device.

[0004] This application provides an opening assembly for connection to a camera device. The opening assembly includes an opening and a connecting portion. The opening includes a first end and a second end opposite to each other, and has a through hole penetrating the first end and the second end. The opening supports the lips. The connecting portion is connected to the first end of the opening, and at least a portion of the connecting portion extends circumferentially away from the opening. The connecting portion has a connecting sub-portion for connection to the camera device, and when the connecting sub-portion is connected to the camera device, the camera lens of the camera device is opposite to the through hole. On a projection plane perpendicular to the extension direction of the through hole, the projection of at least a portion of the connecting sub-portion is offset from the projection of the through hole.

[0005] The opening of the mouthpiece in this application is connected to the main unit of the camera device through a connecting part, thereby realizing an indirect connection between the opening and the main unit. Compared with the opening being directly connected to the main unit, the connection position between the mouthpiece and the main unit is shifted. The projection of the opening is located in the projection plane of the connecting part. Therefore, the position of the mouthpiece connected to the main unit and the position of the opening are decoupled (the position of the through hole). That is, the position of the mouthpiece connected to the main unit and the position of the opening are not related. On the one hand, the through hole can be within the coverage area of ​​the main unit or protrude relative to the main unit, that is, extend beyond the coverage area of ​​the main unit. The position of the through hole of the opening relative to the main unit is more versatile. On the other hand, disposable consumables (isolation covers) are easier to fit onto the mouthpiece.

[0006] In some embodiments, on a projection plane perpendicular to the extension direction of the through hole, the projection of the opening is located within the projection of the connection portion.

[0007] The opening device does not occupy additional space in the direction of the projection plane perpendicular to the extension direction of the through hole, making the structure of the opening device more compact and reducing the size of the opening device.

[0008] In some embodiments, the connecting portion further includes a connecting body. The connecting body includes a first side and a second side opposite to each other in the thickness direction, and a first end of the opening is connected to the first side of the connecting body. The connecting sub-portion includes a flange extending from the second side of the connecting body in a direction away from the first side of the connecting body.

[0009] The connecting body restricts the relative movement of the opening device in the thickness direction, ensuring that the opening assembly and the main body of the camera device do not shift. The flange restricts the relative movement of the opening device in the direction perpendicular to the thickness direction, thereby further securing the opening device to the camera device and improving the stability of the camera device when capturing images.

[0010] In some embodiments, the connecting sub-part includes at least two opposing flanges, or at least three consecutive flanges.

[0011] The two opposing flanges restrict the relative movement of the opening device between the two flanges, preventing the opening device from sliding or shifting. The connecting part includes at least three continuous flanges, which form a "C"-shaped wrapping structure. This not only provides double locking to the opening device from two directions, but the flange in the middle of the three flanges can connect the two flanges, increasing the connection strength of the flanges and ensuring that the opening device will not easily detach or loosen from the camera device.

[0012] In some implementations, the flange is used for snap-fitting or sliding connection with a camera device.

[0013] The opening device connects to the camera equipment via a snap-fit ​​or sliding connection using a flange, eliminating the need for the opening to directly bear the frictional forces generated during the sliding or snap-fit ​​process. This reduces mechanical wear on the opening and extends its lifespan. The snap-fit ​​or sliding connection structure is relatively simple and inexpensive.

[0014] In some embodiments, the connecting portion includes a connecting body, the connecting body including an adjacent and connected first side and a second side, a first end of the opening being connected to the first side, and the connecting sub-part being located on the second side.

[0015] When a user needs to hold the camera to take images, the connecting part is located on the second side and connects to the main unit of the camera, allowing the user to hold the camera vertically, meaning the length of the camera is perpendicular to the horizontal plane. This vertical grip is ergonomic, making the user's grip more natural and comfortable. It also helps the user adjust the angle more easily, ensuring the camera is accurately aimed at the desired area.

[0016] In some embodiments, the connecting body is provided with a receiving groove that extends through the second side and is used to receive the energy receiving component of the camera device, through which the camera of the camera device passes and corresponds to the through hole.

[0017] The receiving slot can serve as a guide channel for the camera, guiding the camera through and aligning it with the through hole, thereby ensuring that the positional relationship between the camera and the through hole is consistent and reducing image quality problems caused by positional deviation.

[0018] In some embodiments, the receiving groove extends through at least a portion of the first side surface, and the opening at least partially covers the receiving groove.

[0019] The receiving slot provides a positioning function, facilitating the installation of the energy receiving component. The receiving slot extends through at least part of the first side, clearly defining the connection position and direction between the opening and the energy receiving component. This ensures the connection position and direction of the opening are unique, providing good foolproof protection and preventing incorrect installation. The opening at least partially covers the receiving slot, allowing the distance between the camera and the opening to be closer, reducing the obstruction of the camera's field of view by the opening.

[0020] In some embodiments, the connecting sub-part includes a magnetic chuck located on the second side.

[0021] The magnetic connection method uses magnetic force to connect and disconnect the connector and camera device. It can automatically align and connect without the need for external force, saving time and manpower, and reducing the wear and loosening problems that may occur with mechanical locks.

[0022] In some embodiments, the connecting sub-part includes a snap-fit ​​structure or a sleeve structure located on the second side.

[0023] The snap-fit ​​and socket-fit structures simplify the assembly process between the opening device and the camera equipment, and improve the reliability and stability of the connection.

[0024] In some embodiments, the through hole of the opening is an oblong hole, an elliptical hole, a rectangular hole, or a flattened oval hole, and the major axis of the cross-section of the through hole is approximately parallel to the second side surface.

[0025] When a user holds the camera device and adjusts the position of the mouthpiece, the orientation of the through-hole can better adapt to the user's natural hand gestures. For example, when holding the camera device vertically (i.e., the length direction of the camera device is perpendicular to the horizontal plane), the long axis of the through-hole's cross-section has greater freedom to accommodate this movement, allowing the mouthpiece to move smoothly along the direction of the teeth while maintaining a stable connection, without worrying that the mouthpiece will fall off the camera device due to lateral forces.

[0026] In some embodiments, the connecting portion further includes a connecting body, the connecting body including a first side and a second side opposite to each other in the thickness direction, the first end of the opening being connected to the first side of the connecting body, and the connecting sub-part including a magnetic attraction structure disposed on the connecting body.

[0027] The connecting body has a large area, and the magnetic structure can be made larger to enhance the connection strength between the connecting body and the camera device.

[0028] In some embodiments, the opening includes an inner cylinder and an outer cylinder, the outer cylinder includes a connecting end and a free end, the connecting end is connected to the connecting portion, the free end is connected to one end of the inner cylinder, the outer cylinder is located outside the inner cylinder, and the outer cylinder and the inner cylinder are spaced apart to clamp a cylindrical receiving cavity.

[0029] The cavity between the inner and outer cylinders can be fitted onto the opening device to provide protection.

[0030] In some embodiments, the cross-sectional area of ​​the connecting end of the outer cylinder is greater than or equal to the cross-sectional area of ​​the free end.

[0031] When an opening device needs to be placed inside the outer cylinder, the cross-sectional area of ​​the connecting end of the outer cylinder is greater than or equal to the cross-sectional area of ​​the free end, thus forming a structure that gradually decreases from the connecting end to the free end, so that the outer cylinder can be fitted onto the opening device.

[0032] In some embodiments, on a projection plane perpendicular to the extension direction of the through hole, the geometric center of the through hole does not coincide with the geometric center of the connection portion.

[0033] The geometric center of the through hole does not coincide with the geometric center of the connector. The part of the connector that is not located around the geometric center of the through hole can be used to connect to the host. On the one hand, the position of the through hole relative to the host can be flexibly adjusted. On the other hand, the position of the through hole does not occupy the host space, allowing the user to hold the host more and improving the stability of the user's grip.

[0034] In some embodiments, the geometric center of the through hole is offset away from the geometric center of the connector from the connector sub-part.

[0035] The geometric center of the through-hole is offset away from the geometric center of the connector from the connector sub-part. Therefore, the through-hole is no longer directly aligned with the connector sub-part, providing greater flexibility in its position. Users can adjust the through-hole to the most suitable position according to their actual needs, whether closer to or farther from the main unit, ensuring the camera accurately targets the area. This also facilitates adjusting the camera's shooting angle.

[0036] In some embodiments, the through hole of the opening is an oblong hole, an elliptical hole, a rectangular hole, or a flattened oval hole. The opening is approximately rectangular on a projection plane perpendicular to the extension direction of the through hole, and the major axis of the cross-section of the through hole is parallel to the short side of the opening.

[0037] When using the camera device, the user holds the mouth opener in their mouth. With the main unit held vertically, the long axis of the main unit is perpendicular to the horizontal plane. The long axis of the cross-section of the through hole is parallel to the short side of the opening. The long axis of the cross-section of the through hole is also parallel to the horizontal plane, which can adapt to the shape of the mouth after it is opened. At this time, the camera can be naturally aligned with the human mouth. The user can take pictures without raising their arm or adjusting the angle of the main unit.

[0038] In some embodiments, the opening and the connecting portion are an integral structure.

[0039] The opening and the connecting part are an integral structure, which can improve the bonding strength between the opening and the connecting part and prevent the opening and the connecting part from separating during the operation of the opening device, thereby ensuring the stability and reliability of the opening device.

[0040] In some embodiments, the opening and the connecting portion are separate structures, and the opening and the connecting portion are detachably connected.

[0041] The detachable connection facilitates the disassembly and maintenance of the opening and the connection. When the opening or the connection is damaged or worn, they can be easily separated, and the damaged part can be replaced individually without replacing the entire opening device, thus reducing maintenance costs.

[0042] In some embodiments, the opening and the connecting portion are separate structures, and the opening and the connecting portion are non-detachably connected.

[0043] The non-detachable connection method ensures a firm connection between the opening and the connecting part, thus enabling it to withstand greater forces during use and preventing loosening or separation.

[0044] In some embodiments, the opening is made of thermoforming material.

[0045] Vacuum-formed mouth openers can be used as single-use items, discarding them after each use to avoid the risk of cross-infection. The cost of blister material is also relatively low, reducing the overall cost of the mouth openers.

[0046] In some embodiments, the opening is made of an opaque material.

[0047] An opening made of opaque material can concentrate light and prevent stray light from entering the through-hole, ensuring that there is no stray light interference when the camera is shooting and improving the image clarity.

[0048] In some embodiments, the opening device includes an opening and a connecting portion connected to each other. The opening has a through hole penetrating opposite a first end and a second end, and includes an inner sidewall located within the through hole and an outer sidewall opposite to the inner sidewall. The opening device also includes a partition cover. The partition cover includes an inner cylinder and an outer cylinder. The inner cylinder is used to extend into the through hole and fits against the inner sidewall. One end of the outer cylinder is connected to one end of the inner cylinder, and the outer cylinder is sleeved outside the inner cylinder. The outer cylinder and the inner cylinder are spaced apart and together form a receiving cavity for accommodating at least a portion of the opening. The outer cylinder fits against the outer sidewall.

[0049] The isolation shield provides good isolation between different users, preventing cross-infection or bacterial transmission caused by direct contact with the opening, thus improving the hygiene and safety of camera equipment.

[0050] In some embodiments, on a projection plane perpendicular to the direction from the first end to the second end, the projection of the opening is located within the projection plane of the connecting portion, and the isolation cover further includes an extension that is connected to the other end of the outer cylinder and is used to fit or connect with the connecting portion.

[0051] The extension can cover at least part of the connection part, preventing users from contaminating the connection part with their mouths, preventing cross-infection or bacterial transmission caused by users directly contacting the connection part, and improving the hygiene and safety of the camera equipment.

[0052] In some embodiments, the isolation cover is a one-piece molded structure, which can improve the structural strength of the isolation cover.

[0053] In some embodiments, the shield is made of thermoformed material.

[0054] Isolation shields made of blister packaging material can be used as disposable items, which can be discarded after each use, avoiding the risk of cross-infection. Blister packaging material is also inexpensive, reducing the cost of the isolation shields.

[0055] In some embodiments, the cross-section of the end where the outer cylinder connects to the inner cylinder is smaller than or equal to the cross-section of the other end.

[0056] When an opening device needs to be placed inside the outer cylinder, the cross-sectional area of ​​the connecting end of the outer cylinder is greater than or equal to the cross-sectional area of ​​the free end, thus forming a structure that gradually decreases from the connecting end to the free end. Therefore, the outer cylinder can be fitted onto the opening device.

[0057] This application also provides an opening assembly. The opening assembly includes the opening device described in any of the above embodiments.

[0058] In the opening assembly, the opening of the opening device is connected to the main unit of the camera device through the connecting part, thereby realizing the indirect connection between the opening and the main unit. Compared with the opening being directly connected to the main unit, the connection position between the opening device and the main unit is shifted. The projection of the opening is located in the projection plane of the connecting part. Therefore, the position of the opening device connected to the main unit and the position of the opening are decoupled (the position of the through hole). That is, the position of the opening device connected to the main unit and the position of the opening are not related. On the one hand, the through hole can be within the coverage area of ​​the main unit or protrude relative to the main unit, that is, extend beyond the coverage area of ​​the main unit. The position of the through hole of the opening relative to the main unit is more versatile. On the other hand, disposable consumables (isolation covers) are easier to fit onto the opening device.

[0059] This application also provides a camera device. The camera device includes a main unit, an energy receiving component connected to the main unit, and an opening as described in any of the above embodiments. The energy receiving component includes a support arm and a camera mounted on the support arm, the support arm extending from the main unit; the connecting sub-part of the connecting portion is connected to the main unit, and the camera is opposite to the through hole.

[0060] In camera equipment, the opening of the mouthpiece is connected to the main unit of the camera equipment through the connecting part, thereby realizing the indirect connection between the opening and the main unit. Compared with the opening being directly connected to the main unit, the connection position between the mouthpiece and the main unit is shifted. The projection of the opening is located in the projection plane of the connecting part. Therefore, the position of the mouthpiece connected to the main unit and the position of the opening are decoupled (the position of the through hole). That is, the position of the mouthpiece connected to the main unit and the position of the opening are not related. On the one hand, the through hole can be within the coverage area of ​​the main unit or protrude relative to the main unit, that is, extend beyond the coverage area of ​​the main unit. The position of the through hole of the opening relative to the main unit is more versatile. On the other hand, disposable consumables (isolation covers) are easier to fit onto the mouthpiece.

[0061] In some embodiments, the end of the support arm is connected to the host computer, and the camera is disposed on the peripheral side of the support arm.

[0062] With the camera positioned on the periphery, the user can hold the main unit vertically, ensuring its length is roughly perpendicular to the horizontal plane and its width and thickness are roughly parallel to it. In this position, the periphery of the camera naturally aligns with the human mouth, allowing the user to take pictures without raising their arm or adjusting the unit's angle. This more natural and comfortable grip reduces arm fatigue and helps the camera stay firmly aimed at the target, resulting in clearer and more stable images of the mouth.

[0063] In some implementations, the connecting sub-part is connected to the periphery of the host.

[0064] The connecting part can restrict the relative movement of the opening device in the thickness direction perpendicular to the main body, ensuring that the opening assembly and the main body do not shift, thereby further fixing the opening assembly to the main body.

[0065] In some embodiments, the connecting sub-part is connected to one end of the main unit where the support arm is located.

[0066] The connecting part is connected to one end of the main unit with a support arm, which shortens the distance between the opening device and the camera, making it easier to align the camera and the through hole.

[0067] In some implementations, the connecting sub-part is connected to the host and the camera facing the same side.

[0068] The connecting part is positioned on the same side as the main unit and the camera, ensuring that the connection between the opening device and the camera device is more intuitive and easy to operate. Users can quickly complete the installation without having to make additional adjustments to the angle or direction, simplifying the assembly process and reducing the possibility of incorrect assembly.

[0069] In some embodiments, the connecting portion is sleeved on the host.

[0070] The connecting part is directly fitted onto the main unit, which provides support for the mouth opener, ensuring a more secure connection between the mouth opener and the main unit.

[0071] In some embodiments, the host has two perpendicular length directions, width directions, and thickness directions, and the surface formed by the long side and the wide side of the host is the maximum surface of the host. On a projection plane parallel to the maximum surface, at least a portion of the opening is connected to or attached to the maximum surface of the host.

[0072] The flat surface formed by the long and wide sides of the main unit is its largest surface, giving it a relatively flat shape. This allows for greater contact between the largest surface and the user's palm, resulting in a more comfortable grip and better control, thus ensuring camera stability. Furthermore, the camera lens can be roughly parallel to the largest surface of the unit, making it easier to hold during use.

[0073] In some embodiments, on a projection plane perpendicular to the thickness direction of the host, the area of ​​the projection plane of the host is larger than the area of ​​the projection plane of the support arm, and the connecting portion is connected to one end of the support arm of the host in the thickness direction near the energy receiving component.

[0074] The main unit has a large projected area, which provides a larger connection position for the connecting parts, making the connection between the connecting parts and the main unit more robust and reliable, and enhancing the overall strength of the structure.

[0075] In some embodiments, in the longitudinal extension direction of the host and the support arm, the cross-section of the host is larger than the cross-section of the support arm; and / or, the cross-section of the support arm is not greater than 300 mm. 2 ; and / or, the width of the support arm is not greater than 20mm, and the thickness of the support arm is not greater than 15mm.

[0076] By controlling the cross-section, width, and thickness of the support arm, the overall volume of the support arm can be controlled. This reduces the risk of the support arm colliding with teeth, and the smaller width allows for more flexible movement of the support arm within the oral cavity, improving the comfort and safety of the energy receiving component.

[0077] In some embodiments, the through hole of the opening is an oblong hole, an elliptical hole, a rectangular hole, or a flattened oval hole, and the minor axis of the cross-section of the through hole is parallel to the length extension direction of the main unit and the support arm.

[0078] The minor axis of the through-hole's cross-section is parallel to the length extension direction of the main unit and support arm. This allows the through-hole's orientation to better accommodate the user's natural hand gestures when holding the camera device and adjusting the position of the mouthpiece. For example, when holding the camera device vertically (i.e., the length direction of the camera device is perpendicular to the horizontal plane), the major axis of the through-hole allows for greater freedom of movement, enabling the mouthpiece to move smoothly along the direction of the teeth while maintaining a stable connection. Users can more easily slide the mouthpiece up and down or left and right without worrying about it falling off the camera device due to lateral forces.

[0079] In some implementations, the camera does not extend into the through-hole.

[0080] The camera does not extend into the through-hole, allowing the entire depth of the through-hole to be fully utilized, ensuring the imaging distance between the camera and the target area. Since the camera is not located inside the through-hole, it does not interfere with the structure inside the through-hole in the thickness direction, simplifying the removal of the opening device from the main unit and preventing damage to the camera.

[0081] In some embodiments, the connecting portion is provided with a receiving groove that extends through the second side surface, at least a portion of the energy receiving component is received in the receiving groove, and the camera of the energy receiving component passes through and corresponds to the through hole.

[0082] The shape and size of the receiving slot match the outer contour of at least a portion of the energy receiving component, thereby ensuring a clearance fit between at least a portion of the energy receiving component and the inner wall of the receiving slot. This enhances the fixation and support of the receiving slot for at least a portion of the energy receiving component, ensuring a stable installation of the support arm and preventing the at least a portion of the energy receiving component from shifting or loosening. The receiving slot also has a positioning effect, facilitating the installation of at least a portion of the energy receiving component.

[0083] In some embodiments, the host is provided with a first magnetic element and a magnetic suction element is provided on the second side. The first magnetic element and the magnetic suction element generate a magnetic attraction force to connect the connecting part and the host.

[0084] The first magnetic component and the magnetic suction component are fixed by magnetic force through a magnetic connection, ensuring a stable and reliable connection that effectively prevents the mouth opener from loosening or falling off due to external forces during use. Furthermore, the magnetic connection also has a certain self-alignment function, ensuring that the mouth opener and the main unit are quickly aligned during connection, improving the efficiency and accuracy of equipment assembly.

[0103] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 The camera device 100 is a device equipped with a camera 33. The camera device 100 includes at least a main unit 10 and a camera 33. The camera 33 can receive light reflected from the area to be scanned, convert the light into an electrical signal, and then a sensor converts the electrical signal into an image. That is, the camera device 100 can capture images through the camera 33. The main unit 10 of the camera device 100 is used to process the images captured by the camera 33, and to perform operations such as image storage, editing, and format conversion. For example, the main unit 10 can also control the parameter settings of the camera 33, such as focal length, aperture, and shutter speed, to adapt to different shooting scenarios and needs. The main unit 10 is also the part of the camera device 100 that the user holds during use. For example, the camera device 100 can be a mobile phone, an oral scanner, etc.

[0104] In the field of dentistry, it is often necessary to capture images of the oral cavity to analyze the condition of the teeth and other structures within the user's mouth. Common oral images include, but are not limited to, images of the occlusal surface of teeth, images of the inner surface of teeth, and images of the outer surface of teeth. To capture images of the occlusal surface and the inner surface of teeth, the camera 33 needs to be inserted into the oral cavity; to capture images of the outer surface of teeth, a mouth opener 51 is needed to open the user's lips so that the outer surface of the teeth is within the imaging range of the camera 33 for imaging. It is understood that when using the mouth opener 51, the camera 33 is located outside the oral cavity, and the mouth opener 51 is at least partially located inside the oral cavity.

[0105] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 This application provides an opening device 51 for an opening assembly 50, which is used to connect to a camera device 100. The opening device 51 includes an opening portion 511 and a connecting portion 513. The opening portion 511 includes a first end 501 and a second end 502 opposite to each other, and has a through hole 5111 passing through the first end 501 and the second end 502. The opening portion 511 is used to support the lips. The connecting portion 513 is connected to the first end 501 of the opening portion 511, and at least a portion of the connecting portion 513 extends in the circumferential direction of the opening portion 511 in a direction away from the opening portion 511. The connecting portion 513 has a connecting sub-portion 5133 for connecting to the camera device 100, and when the connecting sub-portion 5133 is connected to the camera device 100, the camera 33 of the camera device 100 is opposite to the through hole 5111. On a projection plane perpendicular to the extension direction of the through hole 5111, the projection of at least a portion of the connecting sub-portion 5133 is offset from the projection of the through hole 5111.

[0106] Specifically, the opening assembly 50 is used to connect to the host 10. The connection method can be detachable or non-detachable. The opening assembly 50 includes an opening device 51. When the user takes a picture of the oral cavity using the camera device 100, the opening is used to open the user's lips. The opening portion 511 of the opening device 51 includes a first end 501 and a second end 502 facing each other. The first end 501 of the opening assembly 50 is used to connect to the connecting portion 513, and the second end 502 of the opening assembly 50 is a free end 51153, which can contact the user's lips, gums, etc. A through hole 5111 passes through the first end 501 and the second end 502 of the opening device 51. When the opening assembly 50 is installed on the camera device 100, the camera 33 of the camera device 100 is opposite to the through hole 5111, the area to be scanned (e.g., the outer surface of the teeth) is closer to the second end 502 of the opening device 51, and the camera 33 is closer to the first end 501 of the opening device 51.

[0107] More specifically, the second end 502 of the mouth opener 51 can abut against the user's gums or other areas to open the user's lips. When the user has at least a portion of the mouth opener 51 close to the first end 501 in their mouth, at least a portion of the mouth opener 51 is located between the lips and gums. Therefore, the mouth opener 51 can prevent the lips from touching the gums. At this time, the outer surface of the teeth can correspond to the through hole 5111, and at least the outer surface of the teeth is within the imaging range of the camera 33. The camera 33 can obtain the reflected signal of the area to be scanned (at least the outer surface of the teeth) through the through hole 5111 to generate an image. In addition, the mouth opener 51 can also support the gums, so that the camera 33 and the teeth can maintain a certain distance, avoiding problems such as blurring due to the distance between the camera 33 and the teeth being too close. When the camera device 100 needs to scan the oral cavity, since the mouth opener 51 maintains a certain distance between the teeth and the camera 33, the teeth can be located within the imaging range of the camera 33, thereby making the image captured by the camera 33 clearer.

[0108] In the opening components of related products, the opening device has no connecting part. The opening device is directly connected to the camera device through the first end of the opening, or the connecting part of the opening device is located within the projection of the through-hole. Since the first end of the opening also needs to be opposite the camera, the connection positions of the opening and the camera, and the opening and the host, are interconnected, thus limiting the placement of the opening and camera relative to the host. For example, the camera typically needs to be placed on the largest surface of the host to ensure that the through-hole opposite the camera has a sufficient cross-sectional area to avoid the inner wall of the through-hole obstructing the camera's imaging range.

[0109] The connecting portion 513 is used to change the connection position between the opening 51 and the camera device 100. Further, the connecting portion 513 is used to transfer the connection position between the opening 51 and the camera device 100 to a position other than the first end 501. The extending direction of the through hole 5111 is either from the first end 501 to the second end 502, or from the second end 502 to the first end 501, which is also the thickness direction Z of the camera device 100. The connecting portion 513 is used to connect the camera device 100 and the opening 51. The circumferential direction of the opening 511 is perpendicular to the thickness direction Z. At least a portion of the connecting portion 513 extends circumferentially away from the opening 511, thereby placing at least a portion of the connecting portion 513 on a projection plane perpendicular to the extending direction of the through hole 5111. Further, on the projection plane perpendicular to the extending direction of the through hole 5111, the projection of at least a portion of the connecting sub-portion 5133 is offset from the projection of the through hole 5111. The portion of the connecting part 5133 that is offset from the projection of the through hole 5111 can be used to connect to the host 10, so that the entire opening 51 can be connected to the host 10. At this time, there is no longer a limitation on the position of the through hole 5111, and the camera 33 does not need to be set on the largest surface of the host 10.

[0110] It should be noted that on the projection plane (i.e., the XY projection plane) perpendicular to the extension direction of the through hole 5111, the projection of at least part of the connecting sub-part 5133 is offset from the projection of the through hole 5111, meaning that the projection of at least part of the connecting sub-part 5133 and the projection of the through hole 5111 have a non-overlapping portion. For example, the geometric center Q of the connecting sub-part 5133 does not coincide with the geometric center P of the through hole 5111. That is, when viewed from the projection plane perpendicular to the extension direction of the through hole 5111, the two geometric centers are not at the same point, but are offset to a certain extent, allowing for more flexible positioning of the camera 33, unrestricted by the position of the through hole. For example, on the projection plane perpendicular to the extension direction of the through hole 5111, at least part of the projection of the connecting sub-part 5133 and the projection of the through hole 5111 have a non-overlapping portion. In other words, a portion of these two projections is completely separate and does not intersect. This arrangement avoids the camera 33 directly aligning with the inner wall of the through hole, preventing obstruction or interference during imaging.

[0111] The opening 511 of the opening device 51 of this application is connected to the host 10 of the camera device 100 through the connecting part 513, thereby realizing the indirect connection between the opening 511 and the host 10. Compared with the opening 511 being directly connected to the host 10, the connection position of the opening device 51 and the host 10 is shifted. The projection of the opening 511 is located in the projection plane of the connecting part 513. Therefore, the connection position of the opening device 51 and the host 10 and the position of the opening 511 are decoupled (the position of the through hole 5111). That is, the connection position of the opening device 51 and the host 10 and the position of the opening 511 are not related. On the one hand, the through hole 5111 can be within the coverage area of ​​the host 10 or protrude relative to the host 10, that is, extend beyond the coverage area of ​​the host 10. The position of the through hole 5111 of the opening 511 relative to the host 10 is more versatile. On the other hand, disposable consumables (isolation cover 53) are easier to fit onto the opening device 51.

[0112] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, on a projection plane perpendicular to the extension direction of the through hole 5111, the projection of the opening 511 is located within the projection of the connecting portion 513.

[0113] Specifically, the projection of the opening 511 is located within the projection of the connecting portion 513, that is, at least a portion of the projection of the connecting portion 513 surrounds the projection of the opening 511. Therefore, the opening device 51 does not occupy additional space in the direction of the projection plane perpendicular to the extension direction of the through hole 5111, making the structure of the opening device 51 more compact and reducing the size of the opening device 51.

[0114] Please see Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the connecting portion 513 further includes a connecting body 5139. The connecting body 5139 includes a first side 51301 and a second side 51302 opposite to each other in the thickness direction Z, and the first end 501 of the opening 511 is connected to the first side 51301 of the connecting body 5139. The connecting sub-portion 5133 includes a flange 5137 extending from the second side 51302 of the connecting body 5139 in a direction away from the first side 51301 of the connecting body 5139.

[0115] Specifically, in this application, the thickness direction Z of the connecting body 5139 is consistent with the thickness direction Z of the camera device 100. A first side 51301 of the connecting body 5139 is used to connect with the opening 511. Exemplarily, the connecting body 5139 extends circumferentially away from the opening 511. A second side 51302 of the connecting body 5139 is used to connect with the connecting sub-part 5133. In some embodiments, the connecting body 5139 and the connecting sub-part 5133 are an integral structure, that is, the connecting body 5139 and the connecting sub-part 5133 are a single unit, thereby improving the bonding strength between the connecting body 5139 and the connecting sub-part 5133, preventing separation of the connecting body 5139 and the connecting sub-part 5133 during operation of the connecting part 513, and thus ensuring the stability and reliability of the operation of the connecting part 513. In other embodiments, the connecting body 5139 and the connecting sub-part 5133 are separate structures, meaning they are two distinct structures. In one example, the connecting body 5139 and the connecting sub-part 5133 can be joined together using a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. In another example, the connecting body 5139 and the connecting sub-part 5133 can be joined together using a non-detachable connection method, including but not limited to bonding or welding.

[0116] The connecting body 5139 can restrict the relative movement of the opening 51 in the thickness direction Z, ensuring that the opening assembly 50 and the main body 10 of the camera device 100 do not shift. The flange 5137 can restrict the relative movement of the opening 51 in the direction perpendicular to the thickness direction Z, thereby further fixing the opening 51 to the camera device 100 and improving the stability of the camera device 100 when capturing images.

[0117] Please see Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the connecting sub-part 5133 includes at least two opposing flanges 5137, or at least three consecutive flanges 5137.

[0118] Specifically, the flange 5137 can be one or more. The connecting sub-part 5133 of this application includes at least two opposing flanges 5137. Opposing surfaces refer to surfaces located on opposite sides of the connecting sub-part 5133. The camera device 100 of this application also includes a length direction X and a width direction Y. The length direction X, width direction Y, and thickness direction Z are mutually perpendicular; it can be understood that the camera device 100 has the greatest length in the length direction X. Exemplarily, in an embodiment including at least two opposing flanges 5137, the connecting sub-part 5133 may include two flanges 5137 parallel to the XZ plane, with the two flanges 5137 located on opposite sides of the connecting body 5139 in the width direction Y. Figure 3 For example, in an embodiment that includes at least two opposing flanges 5137, the connecting sub-part 5133 may include two flanges 5137 parallel to the XZ plane, the two flanges 5137 being located on opposite sides of the connecting body 5139 in the width direction Y, and the connecting sub-part 5133 may include two flanges 5137 parallel to the YZ plane, the two flanges 5137 being located on opposite sides of the connecting body 5139 in the length direction X. Figure 2 For example, in an embodiment that includes at least three continuous flanges 5137, two flanges 5137 may be located on opposite sides of the connecting body 5139 in the width direction Y, and one flange 5137 may be located on any side of the connecting body 5139 in the length direction X and connect to the other two flanges 5137.

[0119] The two opposing flanges 5137 can restrict the relative movement of the opening device 51 between the two flanges 5137, preventing the opening device 51 from sliding or shifting. The connecting sub-part 5133 includes at least three continuous flanges 5137. The three flanges 5137 can form a "C"-shaped wrapping structure, which not only double-locks the opening device 51 from two directions, but also the flange 5137 located in the middle of the three flanges 5137 can connect the two flanges 5137, increasing the connection strength of the flanges 5137 and ensuring that the opening device 51 will not easily fall off or loosen from the camera device 100.

[0120] Please see Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some implementations, the flange 5137 is used for snap-fit ​​or sliding connection with the camera device 100.

[0121] Specifically, in one example, the flange 5137 and the camera device 100 are connected by a snap-fit ​​connection. Quick assembly and disassembly are achieved through the engagement of the snap-fit ​​mechanism. The snap-fit ​​connection eliminates the need for additional locking components such as screws or nuts, saving costs; furthermore, it offers high connection strength and reliability, capable of withstanding repeated assembly and disassembly.

[0122] In another example, the flange 5137 is slidably connected to the camera device 100. The opening 51 can slide along a certain direction (usually the length direction X) of the camera device 100, thereby enabling the connection and separation of the opening 51 from the camera device 100. Exemplarily, the flange 5137 of this application is located on opposite sides of the connecting body 5139 in the width direction Y. Exemplarily, the flange 5137 may be provided with a groove 5134, thereby slidably connecting with the host 10. Therefore, the opening 51 can slide in the length direction X of the camera device 100. There are various sliding connection methods, which are not limited in this application. Exemplarily, a groove or guide rail may be provided on the camera device 100, and the flange 5137 is equipped with a corresponding slider or guide, so that the opening 51 can slide on the camera device 100. In one example, the opening 51 is detachably connected to the camera device 100. The opening 51 can be slidably connected to the camera device 100 via the flange 5137, or it can be slidably detached from the camera device 100. In another example, the opening 51 is not detachably connected to the camera device 100. The opening 51 can slide on the camera device 100 via the flange 5137 to change the positional relationship between the through hole 5111 and the camera 33.

[0123] The aperture 51 is engaged or slidably connected to the camera device 100 via a flange 5137, while the opening 511 does not directly bear the frictional force during the sliding or engaging process. This reduces mechanical wear on the opening 511 and extends its lifespan. The sliding connection structure is relatively simple, low-cost, quick, and flexible, allowing users to change the connection state or relative position of the aperture 51 and the camera device 100 according to different shooting needs.

[0124] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the connecting body 5139 includes an adjacent and connected first side 5131 and a second side 5132, the first end 501 of the opening 511 is connected to the first side 5131, and the connecting sub-part 5133 is located on the second side 5132.

[0125] Specifically, the first side 5131 is perpendicular to the thickness direction Z, and the second side is perpendicular to the length direction X. In some embodiments, the connecting body 5139 includes adjacent and connected first side 5131 and second side 5132. The opening 511 of the opening device 51 is located on the first side 5131, while the second side 5132 is connected to the main unit 10 of the camera device 100. The opening device 51 is connected to the main unit 10 via its second side 5132; that is, the opening device 51 can be connected along the length direction X of the camera device 100.

[0126] When a user needs to hold the camera device 100 to take images, the connection along the length direction X allows the user to hold the camera device 100 vertically, meaning the length direction X of the camera device 100 is perpendicular to the horizontal plane. This vertical grip is ergonomic, making the user's grip more natural and comfortable. It also helps the user adjust the angle more easily, ensuring the camera 33 is accurately aimed at the desired shooting area. Furthermore, the vertical grip helps maintain hand stability, especially during prolonged use or handheld shooting, effectively reducing image blur caused by hand tremors and thus improving image quality.

[0127] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the connecting body 5139 is provided with a receiving groove 51311, which extends through the second side 5132 and is used to receive the energy receiving component 30 of the camera device 100, and allows the camera 33 of the camera device 100 to pass through and correspond to the through hole 5111.

[0128] Specifically, the receiving groove 51311 is used to accommodate at least a portion of the energy receiving component 30 of the camera device 100. The cross-sectional shape of the receiving groove 51311 can be rectangular, circular, or other shapes. Preferably, the shape and size of the receiving groove 51311 match the outer contour of the energy receiving component 30, thereby ensuring a clearance fit between the energy receiving component 30 and the inner wall of the receiving groove 51311. This enhances the fixation and support of the receiving groove 51311 for the energy receiving component 30, ensuring a stable installation of the energy receiving component 30 and preventing it from shifting or loosening. The receiving groove 51311 can also serve as a guide channel for the camera 33, guiding the camera 33 through and aligning it with the through hole 5111, thus ensuring that the positional relationship between the camera 33 and the through hole 5111 is consistent. This reduces image quality problems caused by positional deviations.

[0129] Please see Figure 1 , Figure 4 and Figure 5In some embodiments, the receiving groove 51311 extends through at least a portion of the first side 5131, and the opening 511 at least partially covers the receiving groove 51311.

[0130] Specifically, the receiving slot 51311 has a positioning effect, facilitating the installation of the energy receiving component 30. The receiving slot 51311 extends through at least a portion of the first side panel 5131, clearly defining the connection position and direction between the opening device 51 and the energy receiving component 30. This ensures that the connection position and direction of the opening device 51 are unique, providing a good foolproof effect and preventing incorrect installation. The opening 511 at least partially covers the receiving slot 51311, allowing the distance between the camera 33 and the opening 511 to be closer, reducing the obstruction of the camera 33's field of view by the opening device 51.

[0131] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the connecting part 5133 includes a magnetic member 5135 located on the second side 5132.

[0132] Specifically, the magnetic member 5135 is used to connect the connecting sub-part 5133 and the camera device 100. There may be one or more magnetic members 5135, which is not limited in this application. Exemplarily, the second side 5132 of this application is provided with two magnetic members 5135 spaced apart in the width direction Y.

[0133] The magnetic connection method utilizes magnetic force to connect and disconnect the connector 5133 and the camera device 100. It automatically aligns and connects without external force, saving time and manpower, and reducing wear and loosening problems that may occur with mechanical locks. The opening device 51 is magnetically and detachably connected to the camera device 100, allowing the opening device 51 and the camera device 100 to be connected and disconnected during use.

[0134] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the connecting sub-part 5133 includes a snap-fit ​​structure or a sleeve structure located on the second side 5132.

[0135] Specifically, a snap-fit ​​structure (not shown) or a socket structure (not shown) is used to connect the connector 5133 and the camera device 100. There may be one or more snap-fit ​​structures or socket structures, and this application is not limited to them.

[0136] The snap-fit ​​structure consists of one or more matching protrusions (buckles) and grooves. The buckles are located on the connecting part 5133, and the corresponding grooves are provided on the camera device 100. The user can quickly lock the snap-fit ​​by simply aligning the buckle with the groove and gently pushing it. To ensure a good snap-fit ​​effect, the snap-fit ​​structure allows the user to quickly install or remove the opening device 51 without tools, and maintains a stable connection even under slight vibration or impact, preventing accidental detachment, while also facilitating cleaning and replacement of consumables. The connecting part 5133 is provided with a sleeve structure, which can be one or more, and is not limited in this application. The connecting part 5133 can be sleeved onto the camera device 100. The sleeve structure is generally more durable, can be used for a long time and is not easily damaged, and can also incorporate foolproof features such as asymmetrical shapes or guide keys to avoid incorrect assembly.

[0137] The snap-fit ​​and socket structures simplify the assembly process between the opening device 51 and the camera device 100, and improve the reliability and stability of the connection.

[0138] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the through hole 5111 of the opening 511 is an oblong hole, an elliptical hole, a rectangular hole or a flattened oval hole, and the major axis B2 of the cross-section of the through hole 5111 is approximately parallel to the second side surface 5132.

[0139] Specifically, there can be one or more through holes 5111. On the cross-section obtained by the plane perpendicular to the thickness direction Z, the shape of the through hole 5111 includes, but is not limited to, an oblong, a circle, an ellipse, a rectangle, or a flattened circle. The major axis of the cross-section of the through hole 5111 is the maximum dimension of the cross-section in any direction.

[0140] With the major axis B2 of the through hole 5111 set to be approximately parallel to the second side 5132, the orientation of the through hole 5111 can better adapt to the user's natural hand gestures when the user holds the camera device 100 and adjusts the position of the mouthpiece 51. For example, when holding the camera device 100 vertically (i.e., the length direction X of the camera device 100 is perpendicular to the horizontal plane), the length B2 of the through hole 5111 allows for greater freedom of movement, enabling the mouthpiece 51 to move smoothly along the direction of the teeth while maintaining a stable connection. The user can more easily slide the mouthpiece 51 in the up-down or left-right directions without worrying that the mouthpiece 51 will fall off the camera device 100 due to lateral forces.

[0141] Please see Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the first end 501 of the opening 511 is connected to the first side 51301 of the connecting body 5139, and the connecting sub-part 5133 includes a magnetic structure 5138 disposed on the connecting body 5139.

[0142] Specifically, the magnetic structure 5138 is used to connect the connecting body 5139 and the camera device 100. There can be one or more magnetic structures 5138, which is not limited in this application. It is understood that the surface formed by the long side A1 (side in the length direction X) and the wide side B1 (side in the width direction Y) of the host 10 is the largest surface of the camera device 100, and the connecting sub-part 5133 is connected to or attached to this largest surface. Therefore, since the connecting body 5139 has a large area, the magnetic structure 5138 can be made larger to enhance the connection strength between the connecting body 5139 and the camera device 100.

[0143] The magnetic connection method utilizes magnetic force to connect and disconnect the main body 5139 and the camera device 100. It can automatically align and connect without external force, saving time and manpower, and reducing the wear and loosening problems that may occur with mechanical locks. The opening device 51 is magnetically and detachably connected to the camera device 100, and the camera device 100 can connect and disconnect the opening device 51 during use.

[0144] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 6 In some embodiments, the opening 511 includes an inner cylinder 5113 and an outer cylinder 5115. The outer cylinder 5115 includes a connecting end 51151 and a free end 51153. The connecting end 51151 is connected to the connecting portion 513, and the free end 51153 is connected to one end of the inner cylinder 5113. The outer cylinder 5115 is located outside the inner cylinder 5113, and the outer cylinder 5115 and the inner cylinder 5113 are spaced apart to clamp out a cylindrical receiving cavity 5117.

[0145] Specifically, the connecting end 51151 is closer to the connecting portion 513 than the free end 51153. The outer cylinder 5115 of the opening 511 is located outside the inner cylinder 5113 of the opening 511, thus forming a nested structure between the inner cylinder 5113 and the outer cylinder 5115 of the opening 511, with a certain gap between them, to create a cylindrical receiving cavity 5117 for the opening 511. The inner cylinder 5113 of the opening 511 directly contacts the inside of the patient's mouth, serving to support the lips and teeth, while the outer cylinder 5115 of the opening 511 is responsible for firmly fixing the entire mouth opener 51 to the camera device 100 and protecting the inner cylinder 5113 of the opening 511 from the influence of the external environment. The receiving cavity 5117 of the opening 511 allows users to easily install and replace disposable consumables. Furthermore, since the connecting end 51151 of the outer cylinder 5115 of the opening 511 is connected to the connecting part 513, the entire opening 511 can be more firmly attached to the camera device 100, ensuring stability and accuracy during the shooting process.

[0146] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 6 In some embodiments, the cross-sectional area of ​​the connecting end 51151 of the outer cylinder 5115 of the opening 511 is greater than or equal to the cross-sectional area of ​​the free end 51153.

[0147] Specifically, when it is necessary to place another opening device 51 inside the outer cylinder 5115 of the opening 511, the cross-sectional area of ​​the connecting end 51151 of the outer cylinder 5115 of the opening 511 is greater than or equal to the cross-sectional area of ​​the free end 51153, thereby forming a structure that gradually decreases from the connecting end 51151 to the free end 51153, so that the outer cylinder 5115 of the opening 511 can be fitted onto the opening device 51.

[0148] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 6 In some embodiments, on the projection plane perpendicular to the extension direction of the through hole 5111, the geometric center of the through hole 5111 does not coincide with the geometric center of the connecting portion 513.

[0149] Specifically, in some embodiments, the geometric center of the through-hole 5111 does not coincide with the geometric center of the connecting portion 513 on the projection plane perpendicular to the extension direction of the through-hole 5111. The opening 511 of the aperture 51 is indirectly connected to the host 10 of the camera device 100 via the connecting portion 513, rather than directly connected to the host 10. The connection position between the aperture 51 and the host 10 shifts, causing the projection of the opening 511 to lie within the projection plane of the connecting portion 513. This achieves separation between the connection position of the aperture 51 to the host 10 and the position of the opening 511 (i.e., the position of the through-hole 5111). The relative positions of the two are no longer closely related. Therefore, the through-hole 5111 can be adjusted within the coverage area of ​​the host 10, or it can protrude relative to the host 10, extending beyond its coverage area. This increases the positional selectivity of the through-hole 5111 relative to the host 10, allowing users to flexibly adjust the shooting angle and position according to specific needs, improving the adaptability and accuracy of imaging. Secondly, through indirect connection, the connecting part 513 acts as a buffer, reducing the impact of external forces on the opening 511 and enhancing the overall stability of the device. Even in the event of slight collisions or movement, it can maintain a good working condition. In addition, disposable consumables (such as the isolation cover 53) are easier to fit onto the opening device 51 because the geometric center of the through hole 5111 does not coincide with that of the connecting part 513, making the installation process of consumables smoother, simplifying the operation steps and improving the convenience of use.

[0150] The geometric center of the through hole 5111 does not coincide with the geometric center of the connecting part 513. The part of the connecting part 513 that is not located around the geometric center of the through hole 5111 can be used to connect to the host 10. On the one hand, the position of the through hole 5111 on the host 10 can be flexibly adjusted. On the other hand, the position of the through hole 5111 does not occupy the space of the host 10, allowing the user to hold the host 10 more, thus improving the stability of the user's grip.

[0151] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 6 In some embodiments, the geometric center of the through hole 5111 is offset away from the geometric center of the connecting portion 513 in a direction away from the connecting portion 5133.

[0152] Specifically, the geometric center of the through hole 5111 is offset away from the geometric center of the connecting part 5133, thus the through hole 5111 is no longer directly aligned with the connecting part 5133, providing greater room for position adjustment. Users can adjust the through hole 5111 to the most suitable position according to actual needs, whether closer to or further away from the host 10, ensuring that the camera 33 can accurately align with the target area. This facilitates adjusting the shooting angle of the camera 33.

[0153] Secondly, the offset of the geometric center of the through-hole 5111 away from the connector 5133 helps reduce the impact of external forces on the connector 513. When a user operates the camera device 100 by hand, the force applied by the hand is usually concentrated near the connector 5133. By offsetting the through-hole 5111 away from the connector 5133, these external forces can be effectively dispersed, preventing them from acting directly on the connector 513, thereby enhancing the stability and durability of the entire device. Even in the event of a slight collision or movement, the connector 513 is not easily affected, ensuring stability during shooting.

[0154] Furthermore, the offset of the geometric center of the through-hole 5111 from the geometric center of the connector 5133 further simplifies the installation process of disposable consumables (such as the isolation cover 53). Because the through-hole 5111 is far from the connector 5133, the installation of consumables is not obstructed by the structure of the connector 5133, allowing users to more easily slip the consumables onto the opening device 51, reducing assembly difficulty and improving ease of use. This is particularly important for applications requiring frequent consumable replacement, ensuring quick and convenient installation and replacement each time, maintaining hygiene standards.

[0155] Finally, from a user experience perspective, the offset design of the through-hole 5111's geometric center makes operation more intuitive and comfortable. When holding the camera device 100, the user's natural gestures and line of sight make it easier to align with the offset position of the through-hole 5111, achieving precise shooting without additional adjustments to the grip. This design not only improves the ease of operation but also reduces fatigue that may be caused by unnatural operating postures, enhancing the overall user experience.

[0156] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11In some embodiments, the opening 511 is generally rectangular on the projection plane perpendicular to the extension direction of the through hole 5111, and the major axis B2 of the cross-section of the through hole 5111 is parallel to the short side (i.e., the minor axis B1) of the opening 511.

[0157] Specifically, when a user uses camera device 100, with mouth opener 51 in their mouth and holding the main unit 10 vertically, the major axis of the main unit 10 is perpendicular to the horizontal plane. The major axis B2 of the cross-section of through hole 5111 is parallel to the minor axis B1 of opening 511, and the major axis B2 of the cross-section of through hole 5111 is also parallel to the horizontal plane, which can adapt to the shape of the mouth after opening. At this time, the camera 33 can be naturally aligned with the human mouth, and the user can take pictures without raising their arm or adjusting the angle of the main unit 10. The user's grip is not only more natural and comfortable, but also reduces arm fatigue, which helps the camera 33 to be more stably aligned with the shooting target and obtain clearer and more stable oral images. In addition, when the user has mouth opener 51 in their mouth, when opening 511 moves to different positions to open the lips, the separation direction of opening 511 from the lips will not be perpendicular to the connecting surface, resulting in a more stable connection effect during movement.

[0158] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In one embodiment, the opening 511 and the connecting part 513 are an integral structure.

[0159] Specifically, in some embodiments, the opening 511 and the connecting part 513 are an integral structure, that is, the opening 511 and the connecting part 513 are an integral structure, which can improve the bonding strength between the opening 511 and the connecting part 513, prevent the opening 511 and the connecting part 513 from separating during the operation of the opening device 51, thereby ensuring the stability and reliability of the operation of the opening device 51.

[0160] In another embodiment, the opening 511 and the connecting part 513 are separate structures, meaning they are two distinct structures. In one example, the opening 511 and the connecting part 513 can be joined together using a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. This detachable connection method facilitates the disassembly, assembly, and maintenance of the opening 511 and the connecting part 513. When the opening 511 or the connecting part 513 is damaged or worn, they can be easily separated, and the damaged part can be replaced individually without replacing the entire opening device 51, thus reducing maintenance costs.

[0161] In another example, the opening 511 and the connecting part 513 can be joined together by a non-removable connection method, including but not limited to bonding or welding. A non-removable connection method ensures a firm connection between the opening 511 and the connecting part 513, thereby enabling them to withstand greater forces during use and preventing loosening or separation.

[0162] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the opening 51 is made of thermoforming material.

[0163] Specifically, the mouth opening 51 is made of blister material, meaning the mouth opening 51 itself can also be a disposable material. Blister materials include, but are not limited to, polyvinyl chloride, polyethylene terephthalate, polypropylene, or polystyrene, and are not limited in this application. The mouth opening 51 made of blister material can be used as a disposable item, discarded after each user's use, avoiding the risk of cross-infection. Blister materials are also relatively inexpensive, reducing the cost of the mouth opening 51. It should be noted that a portion of the mouth opening 51 may be made of blister material, such as the opening portion 511, thereby further saving costs.

[0164] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the opening 51 is made of an opaque material.

[0165] Specifically, the opaque material can be a black material, etc. The opening 51 made of opaque material can concentrate light on the one hand and prevent stray light from entering the through hole 5111 on the other hand, ensuring that there is no stray light interference when the camera 33 is shooting, and improving the image clarity.

[0166] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 7 This application also provides an isolation cover 53 for an opening device 51. The opening device 51 includes an opening portion 511 and a connecting portion 513 connected to each other. The opening portion 511 has a through hole 5111 penetrating through a first end 501 and a second end 502, and includes an inner sidewall located within the through hole 5111 and an outer sidewall opposite to the inner sidewall. The isolation cover 53 includes an inner cylinder 531 and an outer cylinder 533. The inner cylinder 531 of the isolation cover 53 is used to extend into the through hole 5111 and fits against the inner sidewall. One end of the outer cylinder 533 of the isolation cover 53 is connected to one end of the inner cylinder 531 of the isolation cover 53. The outer cylinder 533 of the isolation cover 53 is sleeved outside the inner cylinder 531 of the isolation cover 53. The outer cylinder 533 of the isolation cover 53 and the inner cylinder 531 of the isolation cover 53 are spaced apart and together form the receiving cavity 537 of the isolation cover 53. The receiving cavity 537 of the isolation cover 53 is used to accommodate at least a portion of the opening 511. The outer cylinder 533 of the isolation cover 53 is in contact with the outer side wall.

[0167] The isolation cover 53 is used to isolate the user's mouth from the opening 511, preventing direct contact between the mouth and the opening 511.

[0168] The space between the inner cylinder 531 and the outer cylinder 533 of the isolation cover 53 forms a receiving cavity 537 for the isolation cover 53. This cavity 537 accommodates at least a portion of the opening 511, providing additional space for the opening 511 and allowing it to naturally embed into the cavity 537. This also facilitates installation and removal by the user. When the isolation cover 53 is positioned over at least a portion of the opening 511, the inner cylinder 531 of the isolation cover 53 fits against the inner wall of the opening 511, and the outer cylinder 533 of the isolation cover 53 fits against the outer wall of the opening 511, forming a double protective layer. When a user uses the camera device 100, the isolation cover 53 prevents the user's mouth from contacting the outer and inner walls of the opening 511, thus avoiding potential hygiene problems caused by multiple users sharing the camera device 100.

[0169] The isolation cover 53 provides good isolation between different users, preventing cross-infection or bacterial transmission caused by direct contact with the opening 511, and improving the hygiene and safety of the camera equipment 100.

[0170] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 7In some embodiments, on a projection plane perpendicular to the direction from the first end 501 to the second end 502, the projection of the opening 511 is located within the projection plane of the connecting portion 513. The isolation cover 53 also includes an extension 535, which is connected to the other end of the outer cylinder 533 of the isolation cover 53 and is used to fit or connect with the connecting portion 513.

[0171] Specifically, the extension 535 can cover at least part of the connecting part 513. When a user uses the camera device 100, the extension 535 can prevent the user's mouth from contacting at least part of the connecting part 513, thereby effectively avoiding hygiene problems that may arise when multiple users share the camera device 100.

[0172] The extension 535 can cover at least part of the connection part 513, preventing the user's mouth from contaminating the connection part 513, preventing cross-infection or bacterial transmission caused by the user's direct contact with the connection part 513, and improving the hygiene and safety of the camera device 100.

[0173] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 7 In some embodiments, the isolation cover 53 is a one-piece molded structure.

[0174] Specifically, in some embodiments, the opening 511 and the connecting portion 513 are an integral structure, that is, the opening 511 and the connecting portion 513 are a single unit, thereby improving the bonding strength between the opening 511 and the connecting portion 513 and preventing separation of the opening 511 and the connecting portion 513 during the operation of the isolation cover 53, thus ensuring the stability and reliability of the isolation cover 53 during operation. In other embodiments, the opening 511 and the connecting portion 513 are separate structures, that is, the opening 511 and the connecting portion 513 are two different structures. In one example, the opening 511 and the connecting portion 513 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. In another example, the opening 511 and the connecting portion 513 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0175] Furthermore, other structures of the isolation cover 53 (such as the extension 535) can also be integrally formed with the opening 511 and the connecting part 513, which will not be described in detail here.

[0176] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 7 In some embodiments, the isolation cover 53 is made of thermoformed material.

[0177] Specifically, the isolation cover 53 only needs to meet the requirements of the inlet material. Since the isolation cover 53 covers the outer and inner sides of the opening 511, and the opening 511 can support the isolation cover 53, the requirements for hardness and thickness of the isolation cover 53 are relatively low. Exemplarily, the isolation cover 53 is made of a thermoforming material. Thermoforming materials include, but are not limited to, polyvinyl chloride, polyethylene terephthalate, polypropylene, or polystyrene, etc., and are not limited in this application.

[0178] The isolation cover 53 made of blister material can be used as a disposable item, which can be discarded after each user's use, avoiding the risk of cross-infection. The cost of blister material is also low, which can reduce the cost of the isolation cover 53.

[0179] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 ),as well as Figure 7 In some embodiments, the cross-section of the end where the outer cylinder 533 of the isolation cover 53 is connected to the inner cylinder 531 of the isolation cover 53 is smaller than or equal to the cross-section of the other end.

[0180] When it is necessary to place an opening device 51 inside the outer cylinder 533 of the isolation cover 53, the cross-sectional area of ​​the connecting end 51151 of the outer cylinder 533 of the isolation cover 53 is greater than or equal to the cross-sectional area of ​​the free end 51153, thus forming a structure that gradually decreases from the connecting end 51151 to the free end 51153. Therefore, the outer cylinder 533 of the isolation cover 53 can be fitted onto the opening device 51.

[0181] Please see Figures 4 to 11 This application also provides an opening assembly 50. The opening assembly 50 includes an opening device 51 according to any embodiment and an isolation cover 53 according to any embodiment.

[0182] In the opening assembly 50, the opening 511 of the opening device 51 is connected to the host 10 of the camera device 100 through the connecting part 513, thereby realizing the indirect connection between the opening 511 and the host 10. Compared with the opening 511 being directly connected to the host 10, the connection position between the opening device 51 and the host 10 is shifted. The projection of the opening 511 is located in the projection plane of the connecting part 513. Therefore, the connection position between the opening device 51 and the host 10 and the position of the opening 511 are decoupled (the position of the through hole 5111). That is, the connection position between the opening device 51 and the host 10 and the position of the opening 511 are not related. On the one hand, the through hole 5111 can be within the coverage area of ​​the host 10 or protrude relative to the host 10, that is, extend beyond the coverage area of ​​the host 10. The position of the through hole 5111 of the opening 511 relative to the host 10 is more versatile. On the other hand, disposable consumables (isolation cover 53) are easier to fit onto the opening device 51.

[0183] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 This application provides a camera device 100. The camera device 100 includes a main unit 10, an energy receiving component 30 connected to the main unit 10, and an opening 51 according to any of the above embodiments. The energy receiving component 30 includes a support arm 31 and a camera 33 disposed on the support arm 31. The support arm 31 extends from the main unit 10; the connecting sub-part 5133 of the connecting part 513 is connected to the main unit 10, and the camera 33 is opposite to the through hole 5111.

[0184] The host unit 10 is used to scan and detect the user's oral cavity. When the camera device 100 is working, the energy receiving component 30 can capture images of the teeth and / or gums inside the oral cavity. Other components inside the host unit 10 can analyze the images captured by the energy receiving component 30 to determine the current condition of the user's oral cavity, and the user can also intuitively understand the current oral cavity condition through the images captured by the energy receiving component 30.

[0185] The energy receiving component 30 is capable of capturing and receiving light reflected from inside the oral cavity, and the light is processed by the energy receiving component 30 to form an image. The light received by the energy receiving component 30 includes, but is not limited to, natural light, infrared light, and ultraviolet light. There can be one or more energy receiving components 30 (two or more), which is not limited in this application.

[0186] The support arm 31 extends from the main unit 10. When the mouth opener 51 is separated from the main unit 10, the user can hold the main unit 10 and insert the support arm 31 into the oral cavity. The energy receiving component 30 is located outside the mouth opener 51. Exemplarily, the energy receiving component 30 can extend from the mouth opener 51, or the mouth opener 51 can be removed from the main unit 10. That is, in the second configuration, the mouth opener 50 can be connected to the main unit 10 or not. The energy receiving component 30 can move within the oral cavity and can freely change the distance and angle between the energy receiving component 30 and the teeth to capture different images. For example, the energy receiving component 30 can be aligned with the inner surface of the teeth to capture images of at least the inner surface of the teeth, and can also extend into the oral cavity to capture images of the occlusal surface of the teeth.

[0187] When the mouth opener 51 is separated from the main unit 10, the energy receiving component 30 can extend into the oral cavity to capture images of the inner surface and occlusal surface of the teeth, as well as local images of a single tooth, thereby achieving comprehensive imaging of the occlusal surface, inner surface, and outer surface of the teeth.

[0188] Specifically, camera 33 is used to capture images. In one example, camera 33 can be a two-dimensional camera module. In this case, camera 33 collects light within its field of view (light from the area to be scanned) and transmits the light to an image sensor. The image sensor converts the light signal into an electrical signal, and after a series of conversions, a two-dimensional image is finally formed. It is understood that the image sensor can be located in the energy receiving component 30 or in the host 10, and is not limited in this application. For example, camera 33 can be a two-dimensional infrared camera module. In this case, camera 33 can emit infrared light, which illuminates the area to be scanned. A portion of the infrared light is reflected from inside the oral cavity. Camera 33 can capture the reflected infrared light, and the image sensor converts it into a digital signal. After digital signal processing, an infrared image can be generated. For example, the camera 33 can be a two-dimensional ultraviolet camera module. In this case, the camera 33 can emit ultraviolet light. When the ultraviolet light shines on the area to be scanned, a portion of the ultraviolet light will be reflected from the inside of the oral cavity. The camera 33 can capture the reflected ultraviolet light. The ultraviolet light is converted into a digital signal by the image sensor. After the digital signal is processed, an ultraviolet image can be generated.

[0189] In another example, camera 33 can be a time-of-flight camera. The time-of-flight camera first emits a laser pulse that illuminates the area to be scanned. This laser pulse reaches the object being photographed and is reflected back. The time-of-flight camera can calculate the distance from the area to be scanned to the camera by the time the pulse is emitted and the time it reflects back, thereby forming a three-dimensional image. This application uses a two-dimensional camera module as an example for illustration.

[0190] The support arm 31 is used to connect the host 10 and the camera 33, and provides a mounting position for the camera 33. In one example, the support arm 31 and the host 10 can be connected in a detachable manner, including but not limited to snap-fit ​​connections or threaded connections. In another example, the support arm 31 and the host 10 can be connected in a non-detachable manner, including but not limited to adhesive bonding or welding. The mounting relationship between the cameras 33 can also be detachable or non-detachable, which will not be elaborated here.

[0191] The support arm 31 connects the host 10 and the camera 33, enabling an indirect connection between the camera 33 and the host 10. Compared to the camera 33 being directly connected to the host 10, the connection position of the camera 33 and the host 10 is shifted. That is, the connection position of the camera 33 and the host 10 is not related to the position of the opening 511. The camera 33 located on the support arm 31 can protrude relative to the host 10, that is, the camera 33 can extend beyond the coverage area of ​​the host 10. The position of the camera 33 relative to the host 10 is more versatile, making it easier for the camera 33 to be inserted into the oral cavity.

[0192] In the camera device 100, the opening 511 of the opening device 51 is connected to the main unit 10 of the camera device 100 through the connecting part 513, thereby realizing the indirect connection between the opening 511 and the main unit 10. Compared with the opening 511 being directly connected to the main unit 10, the connection position between the opening device 51 and the main unit 10 is shifted. The projection of the opening 511 is located in the projection plane of the connecting part 513. Therefore, the connection position between the opening device 51 and the main unit 10 and the position of the opening 511 are decoupled (the position of the through hole 5111). That is, the connection position between the opening device 51 and the main unit 10 and the position of the opening 511 are not related. On the one hand, the through hole 5111 can be within the coverage area of ​​the main unit 10 or protrude relative to the main unit 10, that is, extend beyond the coverage area of ​​the main unit 10. The position of the through hole 5111 of the opening 511 relative to the main unit 10 is more versatile. On the other hand, disposable consumables (isolation cover 53) are easier to fit onto the opening device 51.

[0193] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the end 311 of the support arm 31 is connected to the host 10, and the camera 33 is disposed on the peripheral side 313 of the support arm 31.

[0194] Specifically, it can be understood that the length X of the main unit 10 is the largest dimension of the main unit 10 in the three directions. Ideally, when a user uses the camera device 100, the main unit 10 is held approximately vertically. Vertical holding means that when the main unit 10 is held, its length X is approximately perpendicular to the horizontal plane, and its width Y and thickness Z are approximately parallel to the horizontal plane. If the camera 33 is located at the end 311, in the first configuration, it is difficult to align the camera 33 and the through-hole 5111. Furthermore, when using the camera device 100, the user needs to raise their arm and maintain a certain angle so that the end 311 of the main unit 10 faces the inside of the mouth for shooting. This posture results in the largest surface of the main unit 10 facing downwards, requiring the user to continuously exert force to maintain the position of their arm and the main unit 10, which can easily cause fatigue and make it difficult to maintain a stable shooting state, affecting the clarity and accuracy of the shooting results.

[0195] If the camera 33 is positioned on the peripheral side 313, the user can hold the main unit 10 vertically, so that the length direction X of the main unit 10 is approximately perpendicular to the horizontal plane, and the width direction Y and thickness direction Z are approximately parallel to the horizontal plane. In this position, the peripheral side 313 where the camera 33 is located can naturally align with the human mouth, allowing the user to take pictures without raising their arm or adjusting the angle of the main unit 10. This more natural and comfortable grip reduces arm fatigue and helps the camera 33 to be more stably aligned with the target, resulting in clearer and more stable images of the mouth.

[0196] Please see Figure 2 , Figure 8 and Figure 9 In some embodiments, the connecting sub-part 5133 is connected to the periphery of the host 10.

[0197] Specifically, the connecting sub-part 5133 is connected to the periphery of the main body 10 and extends from the main body 10 in a direction away from the main body 10 and the opening 511, thereby connecting the opening device 51 to the main body 10. The connecting sub-part 5133 can restrict the relative movement of the opening device 51 in the thickness direction Z perpendicular to the main body 10, ensuring that the opening assembly 50 and the main body 10 do not shift, thereby further fixing the opening assembly 50 to the main body 10.

[0198] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the connecting sub-part 5133 is connected to one end of the main unit 10 where the support arm 31 is provided.

[0199] Specifically, in the length direction X, the connecting part 5133 is connected to one end of the main unit 10 where the support arm 31 is provided, thereby shortening the distance between the opening device 51 and the camera 33, making it easier to align the camera 33 and the through hole 5111.

[0200] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the connecting sub-part 5133 is connected to the host 10 and the camera 33 facing the same side.

[0201] Specifically, the connecting part 5133 is positioned on the same side as the main unit 10 and the camera 33, ensuring a more intuitive and easy-to-operate connection between the opening device 51 and the camera device 100. Users can quickly complete the installation without additional angle or orientation adjustments, simplifying the assembly process and reducing the possibility of incorrect assembly. Furthermore, this layout helps maintain the compactness and balance of the entire device. The connection between the connecting part 5133 and the front of the main unit 10 makes the overall structure more symmetrical, avoiding potential center-of-gravity shifts caused by asymmetrical connections, thus enhancing stability during handheld shooting. Simultaneously, when the connecting part 5133 is located on the same side of the main unit 10 and the camera 33, the impact of the connecting part 513's position on the appearance is minimized, maintaining a clean and professional look. This not only enhances the product's visual appeal but also provides a more comfortable operating experience for users. More importantly, this design ensures that the camera 33 can be directly aligned with the through-hole 5111, reducing interference factors in the light path and improving image quality and accuracy. This is particularly suitable for applications requiring high-precision image capture, such as dental imaging and other medical fields.

[0202] Please see Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the connecting part 513 is sleeved on the host 10.

[0203] Specifically, the connecting part 513 is directly sleeved on the main unit 10, which provides support for the opening device 51, ensuring a more secure connection between the opening device 51 and the main unit 10. Even in the event of slight impact or hand tremors, a stable connection can be maintained, reducing the risk of loosening or detachment caused by external forces, thereby improving the quality and accuracy of imaging.

[0204] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the host 10 has two perpendicular length directions X, width directions Y and thickness directions Z. The surface formed by the long side A1 and the wide side B1 of the host 10 is the maximum surface of the host 10. On the projection surface parallel to the maximum surface, at least a portion of the opening 51 is connected to or attached to the maximum surface of the host 10.

[0205] Specifically, the long side A1 of the main unit 10 has the maximum dimension of the main unit 10 in the length direction X, and the wide side B1 of the main unit 10 has the maximum dimension of the main unit 10 in the width direction Y. The plane formed by the long side A1 and the wide side B1 of the main unit 10 is perpendicular to the thickness direction Z of the main unit 10. As mentioned above, the dimension A of the main unit 10 in the length direction X is the maximum dimension of the main unit 10 in all three directions, and the plane formed by the long side A1 and the wide side B1 of the main unit 10 is the largest surface of the main unit 10. Therefore, the main unit 10 has a relatively flat shape. When the user holds it, the largest surface is in contact with more of the palm, making the grip more comfortable and easier for the user to maintain the grip, thus ensuring the stability of the camera 33. Furthermore, the lens of the camera 33 can be roughly parallel to the largest surface of the body, making it easier to hold during use.

[0206] Please see Figure 1 , Figure 4 and Figure 5 or Figure 2 , Figure 8 and Figure 9 In some embodiments, on the projection plane perpendicular to the thickness direction Z of the host 10, the area of ​​the projection plane of the host 10 is larger than the area of ​​the projection plane of the support arm 31, and the connecting part 513 is connected to one end of the host 10 near the support arm 31 of the energy receiving component 30 in the thickness direction Z.

[0207] Specifically, the larger projected area of ​​the main unit 10 provides a more stable foundation, ensuring the stability of the entire device during use, especially when handheld, making it easier for users to hold the main unit 10 and reducing shaking caused by hand tremors or external impacts. Secondly, the larger projected area of ​​the main unit 10 provides a larger connection position for the connecting part 513, making the connection between the connecting part 513 and the main unit 10 more robust and reliable, enhancing the overall strength of the structure, and maintaining good working condition even when frequently adjusting position or angle. In addition, placing the connecting part 513 on the side of the support arm 31 of the energy receiving component 30 in the thickness direction Z of the main unit 10 not only optimizes space utilization but also simplifies the layout of energy transmission and data communication lines, making the connection more compact and efficient. This layout also helps reduce the impact of external forces on the support arm 31, because the larger area of ​​the main unit 10 can better disperse these forces, protecting the support arm 31 and the camera 33 on it from unnecessary stress. Finally, from a visual and operational perspective, the larger projection area of ​​the main unit 10 provides a clear distinction between the main unit 10 and the support arm 31, allowing users to more intuitively identify and adjust the position of each component during operation, thus improving the convenience and comfort of use.

[0208] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the cross-section of the main unit 10 is larger than the cross-section of the support arm 31 in the length extension direction of the main unit 10 and the support arm 31.

[0209] On the projection plane perpendicular to the length direction X of the host 10, the area of ​​the projection plane of the host 10 is larger than the area of ​​the projection plane of the support arm 31, and the cross-section of the host 10 is larger than the cross-section of the support arm 31. The opening device 51 can obtain a larger connection area and improve the stability of the connection.

[0210] Due to its larger cross-section, the main unit 10 can withstand greater torque and external forces, reducing device wobbling caused by minor collisions or hand tremors and ensuring stability during shooting. The larger cross-section of the main unit 10 provides a larger contact area for the connecting part 513, making the connection between the two more robust. When the connecting part 513 is fixed to the main unit 10, the larger contact area means that the stress distributed on it is more even, reducing the possibility of localized stress concentration and lowering the risk of deformation or damage to the connecting part 513. The larger cross-section of the main unit 10 also provides a clear visual distinction between the main unit 10 and the support arm 31, allowing users to more intuitively identify and adjust the position of each component during operation, improving ease of use and comfort. Furthermore, the larger cross-section of the main unit 10 provides a better grip, especially during handheld shooting, allowing users to hold the main unit 10 more naturally, reducing the possibility of hand fatigue and further enhancing the operating experience.

[0211] The cross-section of the main unit 10 is larger than that of the support arm 31, providing a larger connection area for the opening device 51 and enhancing the stability and reliability of the connection.

[0212] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the cross-sectional area of ​​the support arm 31 is no greater than 300 mm². 2 .

[0213] The cross-sectional area of ​​the support arm 31 can be 213 mm². 2 220mm 2 230mm 2 240mm 2 250mm 2 260mm 2 270mm 2 280mm 2 290mm 2 Or 300mm 2 If the cross-sectional area of ​​the support arm 31 is greater than 300 mm² 2 This could result in the support arm 31 becoming too large, making it difficult to move flexibly inside the mouth, and it might even collide with teeth or other oral structures, affecting the shooting effect and user experience.

[0214] The cross-sectional area of ​​the support arm 31 is no greater than 300 mm². 2On the one hand, it reduces the risk of the support arm 31 hitting the teeth, and on the other hand, the smaller width makes the support arm 31 move more flexibly in the oral cavity, improving the comfort and safety of using the energy receiving component 30.

[0215] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the width C1 of the support arm 31 is not greater than 20 mm, and the thickness C2 of the support arm 31 is not less than 15 mm.

[0216] The width of the support arm 31 is defined as dimension C1 in its width direction Y. Dimension C1 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, or 20mm. If the dimension C1 of the support arm 31 in its width direction Y is greater than 20mm, the support arm 31 may become too large, making it difficult to move flexibly within the oral cavity, and may even collide with teeth or other oral structures, affecting the shooting effect and user experience.

[0217] The dimension C1 of the support arm 31 in its width direction Y is less than or equal to 20mm. On the one hand, this reduces the risk of the support arm 31 hitting the teeth, and on the other hand, the smaller width makes the support arm 31 move more flexibly in the oral cavity, improving the comfort and safety of using the energy receiving component 30.

[0218] The dimension C2 of the support arm 31 in its thickness direction Z can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm. If the dimension C2 of the support arm 31 in its thickness direction Z is greater than 15mm, the support arm 31 may become too large, making it difficult to move flexibly in the oral cavity, and may even collide with teeth or other oral structures, affecting the shooting effect and user experience.

[0219] The dimension C2 of the support arm 31 in its thickness direction Z is less than or equal to 15mm. On the one hand, this reduces the risk of the support arm 31 hitting teeth or other oral structures. On the other hand, the smaller thickness makes the support arm 31 move more flexibly in the oral cavity, improving the comfort and safety of using the energy receiving component 30.

[0220] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the through hole 5111 of the opening device 51 is an oblong hole, an elliptical hole, a rectangular hole or a flat round hole, and the short axis A2 of the cross-section of the through hole 5111 is parallel to the length extension direction of the main body 10 and the support arm 31.

[0221] Specifically, there can be one or more through holes 5111. On the cross-section obtained by the plane perpendicular to the thickness direction Z, the shape of the through hole 5111 includes, but is not limited to, an oblong, a circle, an ellipse, a rectangle, or a flattened circle. The minor axis A2 of the cross-section of the through hole 5111 is the minimum dimension of the cross-section in any direction.

[0222] The minor axis A2 of the cross-section of the through hole 5111 is parallel to the length extension direction of the main unit 10 and the support arm 31, that is, the minor axis A2 of the cross-section of the through hole 5111 is at least parallel to the major axis A1 of the main unit 10. Therefore, when the user holds the camera device 100 and adjusts the position of the mouthpiece 51, the orientation of the through hole 5111 can better adapt to the user's natural hand gestures. For example, when holding the camera device 100 vertically (that is, the length direction X of the camera device 100 is perpendicular to the horizontal plane), the direction of the major axis B2 of the through hole 5111 allows for greater freedom of movement to accommodate this movement, so that the mouthpiece 51 can move smoothly along the direction of the teeth while maintaining a stable connection. The user can more easily slide the mouthpiece 51 in the up-down or left-right direction without worrying that the mouthpiece 51 will fall off the camera device 100 due to lateral force.

[0223] Please see Figure 1 , Figure 4 and Figure 5 (or Figure 2 , Figure 8 and Figure 9 ,or Figure 3 , Figure 10 and Figure 11 In some embodiments, the camera 33 does not extend into the through hole 5111.

[0224] With the mouth opener 51 installed on the host 10, the camera 33 does not extend into the through-hole 5111. The entire depth of the through-hole 5111 can be fully utilized, ensuring the imaging distance between the camera 33 and the target area. This ensures that the camera 33 can obtain the optimal focal length and viewing angle, thereby capturing clearer and more detailed images of the teeth. The depth of the through-hole 5111 acts as a natural guide channel, allowing for consistent distance and angle in each shot, improving the consistency and accuracy of the imaging.

[0225] The camera 33 is not located inside the through hole 5111; that is, in the thickness direction Z, the camera 33 and the structure inside the through hole 5111 do not interfere with each other, which simplifies the process of removing the opening device 51 from the main unit 10. Users do not need to worry about complicated connections or disassembly difficulties caused by the camera 33 being inserted into the through hole 5111. They can easily remove the opening device 51 from the main unit 10 for cleaning, inspection, or replacement of consumables, reducing the risk of damage to the camera 33 or other components during disassembly, and also reducing the difficulty of reinstallation.

[0226] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the connecting part 513 is provided with a receiving groove 51311, which extends through the second side 5132. At least a portion of the energy receiving component 30 is received in the receiving groove 51311, and the camera 33 of the energy receiving component 30 passes through and corresponds to the through hole 5111.

[0227] The receiving groove 51311 is used to accommodate at least a portion of the energy receiving assembly 30 (e.g., the support arm 31). The cross-sectional shape of the receiving groove 51311 can be rectangular, circular, or other shapes. Preferably, the shape and size of the receiving groove 51311 match the outer contour of the support arm 31, thereby ensuring a clearance fit between the support arm 31 and the inner wall of the receiving groove 51311. This enhances the fixation and support of the receiving groove 51311 for the support arm 31, ensuring a stable installation of the support arm 31 and preventing it from easily shifting or loosening. The receiving groove 51311 also has a positioning effect, facilitating the installation of the support arm 31. Furthermore, the receiving groove 51311 is only provided on the first side 5131, clearly defining the connection position and direction of the opening device 51 and the support arm 31. This ensures that the connection position and direction of the opening device 51 are unique, providing a better foolproof effect and preventing incorrect installation.

[0228] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the host 10 is provided with a first magnetic element 13 and a magnetic suction element 5135 is provided on the second side 5132. The first magnetic element 13 and the magnetic suction element 5135 generate a magnetic attraction force to connect the connecting part 513 and the host 10.

[0229] Specifically, the first magnetic element 13 can be one or more, which is not limited in this application. Similarly, the magnetic suction element 5135 can be one or more, which is also not limited in this application. The number of the first magnetic element 13 and the magnetic suction element 5135 can be the same or different. When the mouth opener 51 needs to be connected to the host 10, the first magnetic element 13 and the magnetic suction element 5135 attract each other and combine, thereby completing the connection between the mouth opener 51 and the host 10. When the mouth opener 51 needs to be separated from the host 10, it is only necessary to overcome the magnetic force and manually separate the mouth opener 51 from the host 10.

[0230] The first magnetic component 13 and the magnetic suction component 5135 are connected by magnetic attraction and fixed by magnetic force. The connection is stable and reliable, which can effectively prevent the mouth opener 51 from loosening or falling off due to external force during use. In addition, the magnetic connection also has a certain self-alignment function, which can ensure that the mouth opener 51 and the host 10 are quickly aligned when connected, improving the efficiency and accuracy of equipment assembly.

[0231] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
